| 摘 要： | 为了明确不同施肥种类对旱地红壤肥力与酶活性的影响,以30年（1981年至今）长期定位试验地为基础,研究不同施肥处理（CK,N,NP,NPK,2倍NPK,猪粪,NPK＋猪粪）旱地红壤玉米田耕层（0～20 cm）土壤酶活性与养分的变化趋势及其相关性。结果表明：1）全N含量各处理间差异不显著,单施N肥显著增加土壤速效N,施有机肥处理（NPK＋猪粪,猪粪）土壤的pH值、有机质、全P、速效P均显著增加;2）除了2倍NPK处理土壤脲酶活性最高外,施有机肥土壤的转化酶、脱氢酶、酸性磷酸酶、过氧化氢酶活性也较其他处理显著增加;3）酸性磷酸酶、过氧化氢酶、脱氢酶、脲酶与全N、有机质、速效N呈显著或极显著正相关;因此,红壤旱地通过长期施用有机肥或与无机肥配施,不仅能显著提高土壤肥力,而且能增加土壤酶活性,从而显著提高土壤持续生产力。

| Abstract: | In order to understand the relation between soil enzyme activity and soil chemical propertities in upland red soil under different fertilizer treatments,we conducted a study to determine the effects of pig manure,inorganic fertiliser and combination of pig manure and inorganic NPK on soil chemical and biological properties in a more than 30 a long-term fertilization experiment.The treatments as the following:no fertilization(CK),N,NP,NPK,double NPK,pig manure,NPK+pig manure.The results showed,the total N co... |
